Using your Auren EV v4 Commuter E - Bike is a breeze. First, make sure the battery is fully charged using the 2A fast charger. To start, turn on the bike through the display, and select your desired mode (boost, normal, or eco). Use the Enviolo CVT Internal Gear Hub to change gears smoothly as you ride. When you need to stop, squeeze the Tektro hydraulic disc brakes gently. For maintenance, keep the bike clean, especially after riding in wet or muddy conditions. Wipe down the frame, wheels, and components regularly. Check the tyre pressure of the 700x37C SaturnRing All - Road tyres frequently to ensure a smooth ride. The Panasonic battery should be removed and stored in a cool, dry place when not in use for an extended period. Also, make sure the front pizza rack, if added, is securely attached. If you have any issues, refer to the manufacturer's customer support.
